Saury is a kind of fish, or a kind of edible fish. A variety of criteria can be used to classify fish, such as marine fish and freshwater fish, from the living environment of fish. Their living environment is very different, living in sea water and fresh water, so their habits are relatively different.
In this respect, the saury can be divided into marine fish, because the saury lives in the ocean. Specifically, the main distribution area of saury is the Pacific region. The saury's favorite water temperature ranges from 15 to 18 degrees, so it is more common in mid-latitudes and less common in very low and very high latitudes. In the northern part of the Pacific Ocean, saury is the most abundant. For example, the Japan Sea in the northwest of the Pacific Ocean, the Bering Sea in the north, and some waters near Mexico in the east, etc. In the sea area of our country, there are also saury distribution, mainly in the Yellow Sea and the eastern coast of Shandong Peninsula.
The above has been introduced, saury is a marine fish, mainly distributed in the Pacific region. Therefore, saury has adapted to the environment in the sea. The difference between sea water and fresh water is relatively large, especially the salinity, the salinity of sea water is very high, while the salt content of fresh water is relatively low, can be said to be a great disparity. The saury has adapted to the high salinity environment in the sea, and their physiological regulation mechanism has adapted to the sea environment in the long process of evolution, so if the saury is allowed to enter fresh water, they may not be able to adapt, or even die in a short time, unable to survive.
